After replacing about 35 parts on the 74 455 that sat for 32 years, I took it down the lane to get the mail for 2 days & it ran Great.
But I can never leave well enough alone. 🥴
Put on New GM plug wires, dist cap, rotor, brush and seal...Now has Weak Spark and Just Cranks.
Just ordered the tach clip that's missing.
Put the old rotor, brush & seal back on & no change. Strange!!
Thanks One and All,
Mart

No, but I don't see how the Coil that worked Great 15 minutes earlier could have gone bad just by replacing the Cap, rotor, brush & seal.
I have it set right on TDC now...go from there.
Thanks Kightrider.

Top dead center was pointing toward 8, so just
to see I moved 1 to 8, etc...Still just cranks.
Thanks One and All,
